BOTTLE CLOSURE Filed March 14. 1929 Patented Dec. 29, 1931 UNITED STATES PATENT OFFICE BOTTLE CLOSURE Application filed March 14, 1929, Serial No. 347,130, and in Denmark May 12, 1928.

111g member consists of a disk of paste-board or the like, which covers the rim of the bottle and is held in position by means of a metal band which is passed around the neck of the bottle and is closed by means of a suitable closing mechanism which can be easily released, to a ring. The characteristic feature of the invention consists in the form of said closing mechanism whiehserves to close said band to a ring.

The invention has been illustrated in the accompanying drawings, in which Fig. 1 shows the neck of a bottle on which a corresponding closure is fitted, in vertical section,

Figs. 2 and 3 show the closure in side View and top view, respectively,

Fig. 4 is the band closed to a ring, before it is fitted to the neck of the bottle.

The neck of the bottle a has on its outside a groove 6 which extends all around the bottlcs neck. Over this is fitted a pasteboard disk 0 which rests directly on the rim of the neck of the bottle and is held to the same by means of a. metal band f, for example a strip of sheet metal. This has at its upper edge,

a flange 0, which is produced by the upper edge being pressed inwards and downwards towards the pasteboard disk 0 and as the pressing inwards is performed with a stamp ing tool having many teeth, the flange 0 thereby obtains the appearance of a string of pearls, cfr. Fig. 3. Below the band (Z, is, as it appears from Figs. 1 and 2, pressed into the groove 7) in the neck of the bottle. so that the band is thereby held strongly to the same.

The thickness of the band .is only a fraction of a millimeter but in the drawings the thickness has been greatly exaggerated for greater distinctness.

Fig. 4 shows the metal band (Z after it has been bent together to a ring, but before the flange 6 has been bent over. In the two ends of the band d which overlap one another are provided four incisions k, which are passed through both ends of the band.

Thereby small ears Z are produced, which are first bent towards the pasteboard disk 0 whereupon the other part of the flange e is bent down as shown in Fig. 3. In the bending over towards the ,p-asteboard disc 0 the breadth of the ears Z will not be reduced and these will therefore lie safely beneath the bent over flange c, as the recesses from which the ears are taken will in bending over be reduced in breadth and get the form of trapezoids. Owing to the pearlike appearance the recesses of the ears Z are easily not ced and the ears now so engage in the other part of the flange e that the band 01 is safely and strongly held while at the same time readily opened 1f vigorously seized.

Instead of maklng the closure of two cars (Z that closure may be made with only one such ear, or also with several.

The bottle closure described is remarkable for its cheapness and its comparative strength while at the same time it is easy to open by anyone without the use of any tools whatever.

I claim:

A bottle closure comprising a disk to be placed over the mouth of a bottle, and a disk holding band having overlapping ends, the upper edge of said band having a flange bearing on said disk, and also having a plurality of radial gashes in the top edge of the overlapping ends, whereby two sets of square ears are formed, said ears being bent towards sa d disk, and those of the overlapping end superimposed on and in registry with those of the other end, before the remaining part of the flange is bent down so that the band ends are locked in position by overlapping the said ears.

In witness whereof I affix my signature. 7 YILIIELM CHRISTIAN HEINRICH NIELSEN.
